Title: Systems and methods for performing hand segmentation
Inventor: MAURYA JITENDER KUMAR
IPC: G06K9/00
Filed: 2019-09-05
Abstract: Hand segmentation on wearable devices is a challenging computer vision problem with a complex background due to computational capacity of device(s), different skin tone of users from varied race, and presence of skin color background under varying illumination conditions. Embodiments of the present disclosure provide systems and methods for performing, in real time, hand segmentation by pre-processing an input image to improve contrast and removing noise/artifacts. A multi-orientation matched filter (MOMF) is implemented and applied on the pre-processed image by rotating the MOMF at various orientations to form an edge image which comprises strong edges and weak edges. The weak edges are further removed by using morphological operation. The edge image is then added to the input image (or pre-processed image) to separate different texture regions in an image. The largest skin-color blob is then extracted and considered to be correctly segmented hand.
